Abstract

Across eukaryotic species, mild mitochondrial stress can have beneficial effects on the lifespan of organisms. Mitochondrial dysfunction activates an unfolded protein response (UPR(mt)), a stress signaling mechanism designed to ensure mitochondrial homeostasis. Perturbation of mitochondria during larval development in C. elegans not only delays aging but also maintains UPR(mt) signaling, suggesting an epigenetic mechanism that modulates both longevity and mitochondrial proteostasis throughout life. We identify the conserved histone lysine demethylases jmjd-1.2/PHF8 and jmjd-3.1/JMJD3 as positive regulators of lifespan in response to mitochondrial dysfunction across species. Reduction of function of the demethylases potently suppresses longevity and UPR(mt) induction, while gain of function is sufficient to extend lifespan in a UPR(mt)-dependent manner. A systems genetics approach in the BXD mouse reference population further indicates conserved roles of the mammalian orthologs in longevity and UPR(mt) signaling. These findings illustrate an evolutionary conserved epigenetic mechanism that determines the rate of aging downstream of mitochondrial perturbations.

  • KDM6B/JMJD-3.1 and PHF8/JMJD-1.2 are necessary for lifespan extension induced by mitochondrial dysfunction, and overexpression of either extends lifespan in C. elegans.

    “In addition, KDM6B/JMJD-3.1 and PHF8/JMJD-1.2 are necessary for lifespan extension induced by mitochondrial dysfunction, and overexpression of either of these genes extends lifespan in C. elegans (Merkwirth et al., 2016).”

  • Mice with higher PHF8/JMJD-1.2 expression are longer lived, suggesting link between PHF8 and longevity may be conserved from invertebrates to mammals.

    “Interestingly, mice with higher PHF8/JMJD-1.2 expression are longer lived, suggesting that the link between PHF8/JMJD-1.2 and longevity might be conserved from invertebrates to mammals (Merkwirth et al., 2016).”

  • H3K9 and H3K27 methylation changes are important for UPRmt gene induction in C. elegans, mice, and human cells.

    “changes in the methylation of H3K9 and H3K27 have recently been found to be important for the induction of genes involved in the UPRmt in C. elegans, mice, and human cells (Merkwirth et al., 2016; Tian et al., 2016).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
